CAUTION
R-410A systems operate at higher pressures than R-22 systems. Do not use
R-22 service equipment or components on R-410A equipment.
II. INTRODUCTION
This booklet contains the installation and operating instructions for your package heat
pump. There are a few precautions that should be taken to derive maximum satisfaction
from it. Improper installation can result in unsatisfactory operation or dangerous conditions.
Read this booklet and any instructions packaged with separate equipment required to
make up the system prior to installation. Give this booklet to the owner and explain its pro-
visions. The owner should retain this booklet for future reference.
NOTE: A load calculation must be performed to properly determine the required heating
and cooling for the structure. Also, the duct must be properly designed and installed for
proper airflow. Existing ductwork must be inspected for proper size and sealed system.
Proper airflow is necessary for both user comfort and equipment performance.
IMPORTANT: Proper application, installation and maintenance of this equipment is a must
if consumers are to receive the full benefit for which they have paid.
A. R-410A REFRIGERANT
All units are factory charged with R-410A refrigerant.
1. Specification of R-410A:
Application: R-410A is not a drop-in replacement for R-22; equipment designs must
accommodate its higher pressures. It cannot be retrofitted into R-22 units.
Pressure: The pressure of R-410A is approximately 60% (1.6 times) greater than R-
22. Recovery and recycle equipment, pumps, hoses and the like need to have design
pressure ratings appropriate for R-410A. Manifold sets need to range up to 800 psig
high-side and 250 psig low-side with a 550 psig low-side retard. Hoses need to have a
service pressure rating of 800 psig. Recovery cylinders need to have a 400 psig service
pressure rating. DOT 4BA400 or DOT BW400.
Combustibility: At pressures above 1 atmosphere, mixture of R-410A and air can
become combustible. R-410A and air should never be mixed in tanks or supply
lines, or be allowed to accumulate in storage tanks. Leak checking should never
be done with a mixture of R-410A and air. Leak checking can be performed safely
with nitrogen or a mixture of R-410A and nitrogen.
2. Quick Reference Guide For R-410A
• R-410A refrigerant operates at approximately 60% higher pressure (1.6 times) than R-
22. Ensure that servicing equipment is designed to operate with R-410A.
• R-410A refrigerant cylinders are pink.
• R-410A, as with other HFC’s is only compatible with POE oils.
• Vacuum pumps will not remove moisture from POE oil.
R-410A systems are to be charged with liquid refrigerants. Prior to March 1999, R-
410A refrigerant cylinders had a dip tube. These cylinders should be kept upright for
equipment charging. Post March 1999 cylinders do not have a dip tube and should
be inverted to ensure liquid charging of the equipment.
• Do not install a suction line filter drier in the liquid line.
• A liquid line filter drier is standard on every unit.
• Desiccant (drying agent) must be compatible for POE oils and R-410A
3. Evaporator Coil / TXV
The thermostatic expansion valve is specifically designed to operate with R-410A. DO
NOT use an R-22 TXV. The existing evaporator must be replaced with the factory
specified TXV evaporator specifically designed for R-410A.
4. Tools Required For Installing & Servicing R-410A Models
Manifold Sets:
-Up to 800 PSIG High side
-Up to 250 PSIG Low Side
-550 PSIG Low Side Retard
Manifold Hoses:
-Service Pressure Rating of 800 PSIG

III. CHECKING PRODUCT RECEIVED
Upon receiving the unit, inspect it for any damage from shipment. Claims for damage,
either shipping or concealed, should be filed immediately with the shipping company.
Check the unit model number, heating size, electrical characteristics, and accessories to
determine if they are correct.
IV. EQUIPMENT PROTECTION FROM THE
ENVIRONMENT
The metal parts of this unit may be subject to rust or deterioration in adverse environmen-
tal conditions. This oxidation could shorten the equipment’s useful life. Salt spray, fog or
mist in seacoast areas, sulphur or chlorine from lawn watering systems, and various chem-
ical contaminants from industries such as paper mills and petroleum refineries are espe-
cially corrosive.
If the unit is to be installed in an area where contaminants are likely to be a prob-
lem, special attention should be given to the equipment location and exposure.
1. Avoid having lawn sprinkler heads spray direction on the unit cabinet.
2. In coastal areas, locate the unit on the side of the building away from the waterfront.
3. Shielding provided by a fence or shrubs may give some protection.
4. Elevating the unit off its slab or base enough to allow air circulation will help avoid
holding water against the basepan.
Regular maintenance will reduce the buildup of contaminents and help to protect
the unit’s finish.
1. Frequent washing of the cabinet, fan blade and coil with fresh water will remove most
of the salt or other contaminants that build up on the unit.
2. Regular cleaning and waxing of the cabinet with an automobile polish will provide
some protection.
3. A liquid cleaner may be used several times a year to remove matter that will not wash
off with water.
Several different types of protective coatings are offered in some areas. These coatings
may provide some benefit, but the effectiveness of such coating materials cannot be veri-
fied by the equipment manufacturer.
The best protection is frequent cleaning, maintenance and minimal exposure to
contaminants.

of the units is of the outdoor type, it is important to consult your local code authori-
ties at the time the first installation is made.
B. OUTSIDE SLAB INSTALLATION (Typical outdoor slab installations are shown
in Figures 2 and 3.)
1. Select a location where external water drainage cannot collect around the unit.
2. Provide a level concrete slab extending a minimum 3" beyond all four sides of the
unit. The slab should be sufficient above grade to prevent ground water from
entering the unit. IMPORTANT: To prevent transmission of noise or vibration,
slab should not be connected to building structure.
3. The location of the unit should be such as to provide proper access for inspection
and servicing.
4. Locate unit where operating sounds will not disturb owner or neighbors.
5. Locate unit so roof runoff water does not pour directly on the unit. Provide gutter
or other shielding at roof level. Do not locate unit in an area where excessive
snow drifting may occur or accumulate.
6. It is essential that the unit be elevated above the base pad to allow for conden-
sate drainage and possible refreezing of condensation. Provide a base pad which
is slightly pitched away from the structure. Route condensate off base pad to an
area which will not become slippery and result in personal injury. IMPORTANT:
Do not interfere with openings in bottom of unit.
7. Where snowfall is anticipated, the height of the unit above the ground level must
be considered. Mount unit high enough to be above average area snowfall and to
allow for proper condensate drainage. IMPORTANT: Do not interfere with open-
ings in bottom of unit.
C. CLEARANCES
The following minimum clearances must be observed for proper unit performance
and serviceability.
1. Provide 36" minimum clearance at the front and right side of the unit for service
access. Provide 12" minimum clearance on the left side of the unit for air inlet.
2. Provide 60" minimum clearance between top of unit and maximum 3 foot over-
hang.
3. Unit is design certified for application on combustible flooring with 0" minimum
clearance.
4. See Figure 2 for illustration of minimum installation-service clearances.
D. ROOFTOP INSTALLATION
1. Before locating the unit on the roof, make sure that the strength of the roof and
beams is adequate at that point to support the weight involved. (See specification
sheet for weight of unit.) This is very important and user’s responsibility.
2. For rigging and roofcurb details, see Figures 4 and 5. Use accessory lift brackets
and field-furnished spreaders.
3. For roofcurb assembly, see Roofcurb Installation Instructions.
4. If the roofcurb is not used, provisions for disposing of condensate water runoff
during defrosting must be provided.
5. The unit should be placed on a solid and level roofcurb or platform of adequate
strength. IMPORTANT: Do not interfere with opening in bottom of unit. (See
Figures 6 and 7.)
6. The location of the unit on the roof should be such as to provide proper access for
inspection and servicing.
IMPORTANT: If unit will not be put into service immediately, cover supply and return
openings to prevent excessive condensation.
11
VI. DUCTWORK
Ductwork should be fabricated by the installing contractor in accordance with local
codes, state codes and NFPA90A. Industry manuals may be used as a guide when siz-
ing and designing the duct system - contact Air Conditioning Contractors of America,
1513 16th St. N.W., Washington, D.C. 20036.
Place the unit as close to the space to be air conditioned as possible allowing clearance
dimensions as indicated. Run ducts as directly as possible to supply and return outlets.
Use of non-flammable waterproof flexible connectors on both supply and return connec-
tions at the unit to reduce noise transmission is recommended.
It is preferable to install the unit on the roof of the structure if the registers or diffusers
are located on the wall or in the ceiling. Consider a slab installation when the registers
are low on a wall or in the floor.
On ductwork exposed to outside air conditions of temperature and humidity, use a mini-
mum of 2" of insulation and a vapor barrier. Distribution system in attic, furred space or
crawl space should be insulated with at least 2" of insulation with vapor barrier. One-half
to 1" thickness of insulation is usually sufficient for ductwork inside the air conditioned
space.
Provide balancing dampers for each branch duct in the supply system. Properly support
the ductwork from the structure.
When installing ductwork use noncombustible flexible connectors between ductwork and
unit to reduce noise and vibration transmission into the ductwork.
!
WARNING
DO NOT, UNDER ANY CIRCUMSTANCES, CONNECT RETURN DUCTWORK
TO ANY OTHER HEAT PRODUCING DEVICE SUCH AS A FIREPLACE INSERT,
STOVE, ETC. UNAUTHORIZED USE OF SUCH DEVICES MAY RESULT IN FIRE,
CARBON MONOXIDE POISONING, EXPLOSION, PROPERTY DAMAGE,

VII. FILTERS
Filters are not provided with this unit. They may be supplied and installed in the return
air duct by the installer. A field installed filter grille is recommended for easy and conve-
nient access to the filters for periodic inspection and cleaning. Filters must have ade-
quate face area for the rated air quantity of the unit. See Airflow Performance Table - or
Electrical and Physical Data Table - for recommended filter size.
However, if an internal filter is required, an optional internal filter kit is available which
will work for downflow or horizontal applications. For installation, see Filter Kit
Installation Instruction.

XI. ELECTRICAL WIRING
Field wiring must comply with the National Electrical Code* state and local ordinances
that may apply.
*C.E.C. in Canada
A. POWER WIRING
1. It is important that proper electrical power is available at the unit. Voltage should
not vary more than 10% from that stamped on the unit rating plate. On three
phase units, phases must be balanced within 3%.
2. Install a branch circuit disconnect within sight of the unit and of adequate size to
handle the starting current.
3. For branch circuit wiring (main power supply to unit disconnect), the minimum
wire size can be determined from the circuit ampacity found on the unit nameplate
or from Table F and the National Electrical Code or Canadian Electrical Code.
4. This unit incorporates single point electrical connection for unit and electric heat
accessory.
5. Power wiring must be run in grounded rain-tight conduit. Connect the power field
wiring as follows:
a. NO ELECTRIC HEAT - Connect the field wires directly to the contactor in the
unit control box. Connect ground wire to ground lug.
b. WITH ELECTRIC HEAT - Connect the field wires to the terminal block on the
electric heater kit. Connect the ground wire to the ground lug on the heater kit.
NOTE: For installation of the heater kit, follow the instructions provided with the
heater kit.
6. The pigtail wires in the electric heat box are factory wired to the contactor in the
control box and are protected by internal fuses in the hinged fuse box mounted
under the control box. See label on fuse box cover for fuse sizing.
7. DO NOT connect aluminum field wires to electric heat kit power input terminals.
B. CONTROL WIRING (Class II)
1. Do not run low voltage wiring in conduit with power wiring.
2. Control wiring is routed through the 7/8" hole approximately 11" from the unit top
in the corner post adjacent to the control box. Use a minimum #18 AWG thermo-
stat wire. For wire lengths exceeding 50', use #16 AWG thermostat wire. The low
voltage wires are connected to the unit pigtails which are supplied with the unit in
the low voltage connection box located below the unit control box. See Figure 10.
3. It is necessary that only heat pump thermostats be used. Please contact your dis-
tributor for part number information.
4. Figure 11 shows representative low voltage connection diagrams. Read your ther-
mostat installation instructions for any special requirements for your specific ther-
mostat. These connection diagrams are wired to minimize the amount of auxiliary
electric heaters to be energized during defrost.
NOTE: Units installed in Canada require that an outdoor thermostat (30,000 min.
cycles of endurance) be installed and be wired with C.E.C. Class I wiring.
C. INTERNAL WIRING
1. A diagram of the internal wiring of this unit is located on the electrical control box

XII. INDOOR AIR FLOW DATA
All 208/230 volt units are equipped with multi-speed indoor blower motors. Each unit is
shipped factory wired for the proper speed at a normal external static. See the blower
performance data in this manual.
XIII. CRANKCASE HEAT (OPTIONAL)
At initial startup or after extended shutdown periods, make sure crankcase heat is ener-
gized for at least 12 hours before compressor is started (disconnect switch closed and
wall thermostat “OFF” position).
Crankcase heat is not required on scroll type compressors, but may be necessary for
difficult starting situations.
XIV.PRE-START CHECK
1. Is unit properly located and slightly slanted toward indoor condensate drain?
2. Is ductwork insulated, weatherproofed, with proper spacing to combustible materi-
als?
3. Is air free to travel to and from outdoor coil? (See Figure 2.)
4. Is the wiring correct, tight, and according to unit wiring diagram?
5. Is unit grounded?
6. Are field supplied air filters in place and clean?
7. Do the outdoor fan and indoor blower turn freely without rubbing, and are they tight
on the motor shafts?
8. Has crankcase heat (if required) been on for at least 12 hours?
9. Is unit elevated to allow for outdoor coil condensate drainage during heating opera-
tion and defrost?
XV. STARTUP
1. Turn thermostat to “OFF,” turn “on” power supply at disconnect switch.
2. Turn temperature setting as high as it will go.
3. Turn fan switch to “ON.”
4. Indoor blower should run. Be sure it is running in the right direction.
5. Adjust discharge air grilles and balance system.
6. Turn fan switch to “AUTO.” Turn system switch to “COOL” and turn temperature set-
ting below room temperature. Unit should run in cooling mode.
7. Is outdoor fan operating correctly in the right direction?
8. Is compressor running correctly.
9. Turn thermostat system switch to “HEAT.” Unit should stop. Wait 5 minutes, then
raise temperature setting to above room temperature. Unit should run in heating
mode and after about 30 to 50 seconds auxiliary heaters, if installed, should come
on.
10. Check the refrigerant charge using the instructions located on control box cover.
Replace service port caps. Service port cores are for system access only and will
leak if not tightly capped.
11. Turn thermostat system switch to proper mode “HEAT” or “COOl” and set thermostat

12. Check ducts for condensation and air leaks.
13. Check unit for tubing and sheet metal rattles.
14. Instruct the owner on operation and maintenance.
15. Leave “INSTALLATION” and ”USE AND CARE“ instructions with owner
XVI. OPERATION
Most single phase units are operated PSC (no start relay or start capacitor). It is impor-
tant that such systems be off for a minimum of 5 minutes before restarting to allow
equalization of pressures. Do not move the thermostat to cycle unit without waiting five
minutes. To do so may cause the compressor to stop on an automatic open overload
device or blow a fuse. Poor electrical service can cause nuisance tripping in overloads
or blow fuses.
IMPORTANT: The compressor has an internal overload protector. Under some condi-
tions, it can take up to 2 hours for this overload to reset. Make sure overload has had
time to reset before condemning the compressor.
Some models may be factory equipped with a start relay and start capacitor.
Most single phase 208/240 volt units are equipped with a time delay control (TDC1). The
control allows the blower to operate for up to 90 seconds after the thermostat is satis-
fied.
XVII. AUXILIARY HEAT
The amount of auxiliary heat required depends on the heat loss of the structure to be
heated and the capacity of the heat pump. It is good practice to install strip heat to main-
tain at least 60ºF indoor temperatures in case of compressor failure. The auxiliary heat
is energized by the second stage of the thermostat. The amount of electric heat that is
allowed to come on, as determined by the output of the heat pump, may be controlled by
an outdoor thermostat.
A. CONTROL SYSTEM OPERATION
1. In the cooling mode, the thermostat will, on a call for cooling, energize the com-
pressor contactor and the indoor blower relay. The indoor blower can be operated
continuously by setting the thermostat fan switch at the “ON” position. The revers-
ing valve coil is de-energized when the changeover relay is energized.
2. In the heating mode, the first heat stage of the thermostat will energize the com-
pressor contactor and the indoor blower relay. The second heat stage will turn on
one or more supplementary resistance heaters. The reversing valve is energized
except in defrost. If required or considered desirable, the resistance heat may
also be controlled by outdoor thermostats.

XVIII. DEMAND DEFROST CONTROL AND
HIGH/LOW PRESSURE CONTROLS
The demand defrost control monitors the outdoor ambient temperature, outdoor coil
temperature and the compressor run time to determine when a defrost cycle is
required.
Enhanced Feature Demand Defrost Control: This defrost control has high and
low pressure control inputs with unique pressure switch logic built into the micro-
processor to provide compressor and system protection without nuisance lockouts.
The control cycles the compressor off for 30 seconds at the beginning and the end
of the defrost cycle to eliminate the increased compressor noise caused by rapidly
changing system pressures when the reversing valve switches. See next page for
diagnostic flash codes and sensor resistance values at various temperatures.
DEFROST INITIATION
A defrost will be initiated when the three conditions below are satisfied:
1. The outdoor coil temperature is below 35°F as measured by a good coil sensor,
2. The compressor has operated for at least 34 minutes with the outdoor coil tem-
perature below 35°F and
3. The measured difference between the ambient temperature and the outdoor
coil temperature is greater than the calculated difference determined by the
defrost control microprocessor.
DEFROST TERMINATION
Once a defrost is initiated, the defrost will continue until fourteen minutes has
elapsed or the coil temperature has reached the selected termination temperature.
The factory setting is 70°F but can be changed to 50°F, 60°F, or 80°F by relocating
the jumper on the control board.
TEMPERATURE SENSORS
The coil sensor is located on the outdoor coil near the point fed by the distribution
tubes from the expansion device, on the top most cross-over tube. The ambient air
sensor is located outside the control box so it can sense outdoor temperatures.
If the ambient sensor fails, the defrost control will initiate a defrost every 34 minutes
of compressor run time with the coil temperature below 35°F.
If the coil sensor fails, the defrost control will not initiate a defrost.
TEST MODE
The test mode is initiated by shorting the TEST pins. The unit must have an active
heat pump heating call to enter the test mode. In this mode of operation, the enable
temperature is ignored and all timers are sped up. To initiate a manual defrost,
short and hold the TEST pins. Remove the short when the system switches to
defrost mode after the compressor noise abatement delay. The defrost will termi-
nate on time (14 minutes) or when the termination temperature has been reached.
Test Sequence of Operation:
1) Provide a heating call to the heat pump.
2) Short test pins to bypass anti-short cycle timer. (If unit is running, this step is not
necessary.)
3) Short test pins and hold them shorted to enter defrost mode.
4) Release test pins once control exits noise abatement delay.
5) Monitor coil temperature when control exits defrost.
6) Unit should return to heating mode.
TROUBLE SHOOTING DEMAND DEFROST
During the test mode the coil temperature should be monitored. If the system exits
defrost at approximately the termination temperature, the control is operating norml-
ly. If not, check the coil and ambient temperature sensor resistances, using the sen-
sor temperature vs. resistance table at the end of this section.
Immerse the sensor in water and measure the resistance of the sensor. At 35°F the
resistance of the sensor should be approximately 30,000 ohms.
Ensure that the coil sensor is properly installed that is not loose or touching the cab-
inet.
HIGH/LOW PRESSURE CONTROL MONITORING - ENHANCED
DEFROST CONTROL
Status of high and low pressure controls is monitored by the enhanced feature
demand defrost control and the following actions are taken.
High Pressure Control Provides active protection in both cooling and heating
modes at all outdoor ambient temperatures. The high pressure control is an auto-
matic reset type and opens at approximately 610 psig and closes at approximately
420 psig. The compressor and fan motor will stop when the high pressure control
opens and will start again if the high side pressure drops to approximately 420 psig
where the automatic reset high pressure control resets. If the high pressure control
opens 3 times within a particular call for heating or cooling operation, the defrost
control will lock out compressor and outdoor fan operation.
Low Pressure Control Provides active protection in both heating and cooling
modes at all outdoor ambient temperatures. The low pressure control is an auto-
matic reset type and opens at approximately 15 psig and closes at approximately
40 psig. Operation is slightly different between cooling and heating modes.
Cooling Mode: The compressor and fan motor will stop when the low pressure
control opens and will start again when the low side pressure rises to approxi-
mately 40 psig after the low pressure control automatically resets. If the low
pressure switch opens 3 times within a particular call for cooling operation, the
defrost control will lock out compressor and outdoor fan operation.
Heating Mode: The compressor and outdoor fan motor will stop when the low
pressure control opens and will start again when the low side pressure rises to
approximately 40 psig when the low pressure control automatically resets. If the
low pressure switch trips 3 times within 120 minutes of operation during a par-
ticular call for heating operation, the defrost control will lock out compressor
and outdoor fan operation. If the lock-out due to low pressure occurs at an out-
door ambient temperature below 5°F, the defrost control will automatically exit
the lock-out mode when the outdoor ambient temperature rises to 5°F. This fea-
ture is necessary since the low pressure control could possibly have opened
due to the outdoor ambient being very low rather than an actual system fault.
Exiting Lock-Out Mode: To exit the lock-out mode, remove 24 volts to the defrost
control by removing power to the unit or by shorting the two defrost control pins
together.
